Question

I have a custom JSP tag with an url attribute. How can I pass in the result off invoking another jsp tag to that attribute, specifically using ?

<m:customTag url="<spring:url value='/root'>" />

The value passed in to url is “” rather than what spring resolves the url to. I have done a workaround using RequestContextAwareTag and getRequestContext().getRequestDataValueProcessor() similar to how the spring url tag works. But I would still like to know if the above code is possible to get working.

Answer 1

You could use the var attribute of the url tag.
I think this might help:

<spring:url value="/root" var="someUrl">
<m:customTag url="${someUrl}" />
